I bought one of these when I started last October, have been using it for seven months. No major problems, it works!
Only probs so far:
a castor breaking, replacement requested by email arrived 2 days latert soon fitted and rolling again.
I have changed the connections as I have bought more hose and better tools than those with it
I find it will run 2 x 25' of hose so no longer have to carry it upstairs as I did when new.
Shame you are so far away or you could come and look.
I know I will need a back up as sooner or later it will fail, and am therefore saving up for a Scorpion (approx £2300+vat for machine only) but in the meantime all I can say is I've now done about 150 jobs with the semca.
